Yes, but more expensive to run if they're on continuously.

I have an old PC running as a NAS in the garage, it's not *that* old
so consumes about 40w when idle.  I'm about to replace it with a Pi 4
which is probably nearer 10w or even a bit less when idle.  The saving
isn't huge, I reckon about £1 per watt per year (though it is getting
more expensive of course) so maybe I'll save the cost of the Pi 4 in
around a year or a bit more.  The old PC was getting a bit creaky too,
it's not just a power saving exercise.
